Dear Saint Diotalevi
thank you so much for your reply,
I used the input file:
1 0 domestic_animal
2 1 dog
3 2 terrier
4 2 collie
5 3 fox_terrier
I used your code (only modified for input):
$in = "sample.txt";
open (IN, $in) or die "cant open the in\n";
#
my %dict; # A reverse index on %dict by id.
#
my %dict; # A reverse index on %dict by id.
while (not eof (IN)) {
$line = <IN>;
my ( $id, $parent, $term ) = split (' ', $line, 3) ;
$dict{$id}{'id'} = $id;
$dict{$id}{'parent'} = $parent;
push @{$dict{$parent}{'children'}}, $dict{$id};
}
use Data::Dumper;
print Dumper( \ %dict );
and this is what i get:
$VAR1 = {
'4' => {
'parent' => '2',
'id' => '4'
},
'1' => {
'parent' => '0',
'children' => [
{
'parent' => '1',
'children' => [
{
'parent' => '2'
+,
'children' => [
+ {
+ 'parent' => '3',
+ 'id' => '5'
+ }
]
+,
'id' => '3'
},
$VAR1->{'4'}
],
'id' => '2'
}
],
'id' => '1'
},
'3' => $VAR1->{'1'}{'children'}[0]{'children'}[0],
'0' => {
'children' => [
$VAR1->{'1'}
]
},
'2' => $VAR1->{'1'}{'children'}[0],
'5' => $VAR1->{'1'}{'children'}[0]{'children'}[0]{'children'
+}[0]
};
what I would need is a print out such that each mother term has all its descendents printed to right.
Am I doing something wrong?
Thank you very much,
Ivo

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
